I have officially exhausted all outlets to discover the maker mark and age on this. As Japanese is not a language I am at all familiar with I have been attempting to translate many sites and have had no luck. It has a gold chrysanthemum flower (which is the Japanese seal?) on it that I hope I am not wrong in assuming it is pure as well?This vase is massive - 1500+ grams and I think contains the "Pure Silver" mark at the top and them the bottom would be the signature.

Any and all help would be very much appreciated!

It is similar to this Vase (Obviously the flower is different, I don't have an actual photo of the entire thing, waiting on my mom whom only sent the picture of the marks)

I can only speak for the limitations of my own mental powers, which the OP has confounded with an overwhelming sense of deja vu. I find it very confusing when someone crops a photo previously posted here by another member and reposts it as a different object and writes "it is similar to this..." because I know I have seen the very same object before, but with different marks:

"Similar" is not particularly helpful where either marks or family crests are concerned, since even a seemingly minor difference may point to very different conclusions. If your mother can manage to take a photo of the mark on the bottom of the vase, surely she can take a few photos of the entire object.
